4 Reasons Why You feel Sleepy in Daytime

Do you feel sleepy as soon as you reach your office? Is it hard for you to stay awake during work and other activities and you don’t know why? There can be many reasons behind this. Excessive daytime sleepiness is one of the most common sleep-related patient symptoms, and it affects an estimated 20 percent of the population.

4 Most common causes of excessive daytime sleepiness.

Sleep deprivation

Sleep deprivation is probably the most common and obvious cause of excessive daytime sleepiness. Symptoms can occur in any persons even after mild sleep restriction. Healthy adults should sleep six hours per night. Symptoms of sleep deprivation can occur after only one night of sleep loss in some person. Persons who are chronically sleep deprived are often unaware of their increasing cognitive and performance deficits.

Obstructive sleep apnea

Around 26 to 32 percent of adults are at risk of or have obstructive sleep apnea, and the prevalence is expected to increase. Excessive daytime sleepiness is the most common symptom of Sleep apnea. This is a sleep disorder caused by blockage of the upper airway, results in episodes of cessation of breathing (apneas) or a reduction in airflow (hypopneas). These events induce recurrent hypoxia and repetitive arousals from sleep. This is more common in men than in women. Increasing age and obesity are significant risk factors for sleep apnea.  Persons with apnea have an increased risk of motor vehicle incidents because of their impaired vigilance. Loud snorting, breathing and snoring at night is identifying symptom of obstructive sleep apnea.

Restless leg syndrome

Restless leg syndrome is unusual feeling in your legs, particularly at night which get worse while you’re at rest or sleeping. Because the symptoms are usually worse at night, they can greatly interrupt your sleep and lead to sleepiness when you need to be awake. RLS can be so bad, it is mistaken for insomnia.

Narcolepsy

Narcolepsy is falling into deep sleep anywhere, without warning and most of the time person suffering is unware that he or she was sleeping.

Sedating medications

Sleepiness is the most commonly reported side effect of pharmacologic agents that act on the central nervous system. The modulation of sleep and wakefulness is a complex process involving multiple factors and systems. Although no single chemical neurotransmitter has been identified as necessary or sufficient in the control of sleep, most drugs with clinical sedative or hypnotic actions affect one or more of the central neurotransmitters implicated in the neuromodulation of sleep and wakefulness, including dopamine, epinephrine, norepinephrine, acetylcholine, serotonin, histamine, glutamate, γ-aminobutyric acid, and adenosine.
